TO ALL WHOM IT MAY CONCERN: L v

Beit known that I, AUSTIN LEYDEN, of Atlanta, in the county of Fulton,and State of Georgia, have invented a new and improved CombinationLock;and I do hereby declare that the following is a full, clear, and exactdescription thereofgwhich will enable others skilled in the art to makeand use the same, reference being had to the accompanying drawings,forming part of this specification.

My invention consists in constructing a lock in such a manner that, inapplying it to freight cars of railroads, and to similar purposes, thecar may be locked for through freight, and the destination of the car beindicated by a letter shown on the lock, and so that a way-freight keyfor lthe'sanne lock will no t open it, as will be hereinafter described.

Figure 1 represents the key-hole side of the lock.

Figure 2 represents thc lock with the 'cap or key-hole side oil",showing the' parts of the lock which are operated bythetlirough"i`reigl1t key.

Figure 3 shows-the key-hole side Yturned over, and the parts ofthe lookwhich are operated by the wayfreight key. v

Figure 4 shows the back side of the lock as when applied to acardestined to Chattanooga, for instance, 'the terminus of 'a railroadroute.

Figure 5 is a cross-section ol' iig. 2 through the line :v rv, showingthe through-freight key.

Figure 6 shows the disk-bolt; and v Figure 7v shows the way-freight key,a sidevand an end View.

Similar letters of reference indicate like parts.

v Thislock is really a double lock in one shell, cach part having itsown key, and it is soa'rranged that neither key will operate the lock inthe othcrs place. One key operates it for through freight, and the otherfor'way freight. i y

A represents the disk-bolt. 'This is turned upon its centre (t by thethrough-freight key seen in fig. 5. The letters A; C. W., as seen indottcd lines in fig. 2, are upon its other side; and, whenthe disk isturned and locked bythe key, one of the letters comes opposite the holethrough' the back of' the lock, as seen in iig. 4.

I B is a latch attached to the disk'. There is a small spiral. springunder the inner end, as seen in tig. 5. C C

arc catches attached to the shell of the lock. The disk A cannot beturned by the key until `the end of the latch is lifted out of thecatch. The through key has a. little projection for hearing uponthespring end of the latch and pressing it down, and thereby elevatingthc-other end and lifting it out of the catch, as seen in fig. 5. Inthis example of my invention, the lock` is locked when the latch is atthe two catches marked C', When the latch is at CH it is not locked bythe through key; and the letter shown on the back is W., indicating wayfreight. When the lock is used lin this way, lit is locked by the otherway key. The parts which this key operates are attached to the underside of the cap'or key-hole side of the lock, and seen in iig. 3. Thereis nothing novel or peculiar to this portion, it being similar to theordinary padlock. The key which operates it will not operate thethrough-freight lock, ns already stated; but the bolts of each lock takehold of the same shackle. The shackle does not have a hole at the end,as is usual with the shackles of padlocks; but there are notches orrecesses on the sides of the shackle, in which the bolt rests when thelock is in use. IThe parts of the lock being so plainly shownv in thedrawing, any further description is deemed unnecessary.

Having thus describedmy invention, what I claim as new, and desire tosecure by'Letters Patent, is-

1. The disk-bolt A, constructed substantially as described, withvindicating letters upon one side, and thev latch B attaclled to theother side, and operating substantially as herein shown and described.

2. I claim the catch C C, attached to the shell of the lock,siibstantially as described,in combination with the disk-bolt A, for thepurposes specified. v v

The above lspecilcation of my invention signed by me this day ofNovember, 1866. v

AUSTIN LEYDEN.
